Spacing to mounting height ratio (S/MH) determines the
optimal spacing between fixture centers for uniform
lighting. If the spacing between fixtures exceeds the
optimal spacing determined with the S/MH ratio, then
dark spots may occur on the work plane. All indoor HID
fixtures have a S/MH ratio.
Optimal spacing is calculated by multiplying the S/MH
ratio by the mounting height. For example: If the S/MH
ratio is 1.5 and the mounting height is 15 ft., then the
distance between fixtures should not exceed 1.5 x 15, or
22.5 feet.
Recommended Mounting Heights for HID

Industrial areas can be divided into low bay and high
bay applications. A low bay area is generally one where
mounting heights are 20 feet (6 meters) or less, and a
high bay area is one where mounting heights are over
20 feet (6 meters).
Highbay Fixtures are designed to deliver the maximum
amount of light onto the work plane. They are not
recommended for mounting heights below 20 ft. To
accommodate these higher mounting heights, highbay
fixtures feature reflectors that produce a concentrated
light beam, providing effective horizontal task
illumination. If mounted below 20 ft., highbay fixtures
can cause glare, eye fatigue, harsh shadows, and dark
spots on the work plane.

superbay

High bay luminaires use reflectors to direct light
downward. Low bay luminaires generally include a
refractor to spread out the light for even light distribution and low luminaire brightness. The refractor may be
used alone or in combination with a reflector.

The Superbay Series is designed for many years of
demanding, heavy-duty industrial service. Typical
applications include heavy and light industrial plants,
warehouses, and aircraft hangers as well as retail.

Lowbay Fixtures are designed to deliver a more evenly
spread light onto the work plane. The reflector of low
bay fixtures has an acrylic lens on the bottom to diffuse
the light and provide excellent horizontal and vertical
illumination. This helps to reduce glare while providing a
wider beam pattern to accommodate for lower mounting heights.

The Energy Policy Act of 2005 establishes a long-range energy policy to
combat the nation’s growing energy crisis. Effective January 1, 2006,
through December 31, 2007, the U.S. government is offering substantial,
accelerated tax incentives as a reward for installing or retrofitting energyefficient lighting, HVAC and/or building envelope technologies in qualifying
applications.
Lighting, a critical component of energy use today, represents 40% of the
average commercial building’s electric bill. Energy-efficient upgrades
reduce energy consumption and operating costs by 30 to 50% and often
pay themselves back within months.
The true benefit of EPAct 2005 is that it allows a larger portion of the capital
investment to be depreciated in the first year. Generally, lighting retrofit
investments are amortized over the life of the system, but EPAct 2005
allows a larger portion to be deducted immediately.
EPACT 2005 QUALIFICATIONS

ELECTRONIC E-REG®
Electronic E-Reg® is a new kind of HID ballast – with microprocessor-based technology that delivers a genuine, quantum leap in metal halide performance.
Performance measured by extraordinary, unprecedented lumen maintenance
capabilities means huge opportunities for operating cost reductions, both
through energy savings and lower maintenance requirements. In addition,
Electronic E-Reg® also helps turn color shift, lamp blackening and lack of
control into long-gone problems of the past.
In applications where fluorescent options such as T5/HO are beginning to provide
an HID alternative, users looking for a positive cost/benefit equation now have
more choices – and more ways to enjoy the rewards of better lighting.
REVOLUTIONARY TECHNOLOGY DELIVERS REVOLUTIONARY VALUE
With the introduction of Electronic E-Reg® electronic ballasts for HID systems,
Hubbell Industrial has established totally new benchmarks for performance
and cost savings.

Electronic E-Reg® changes the rules by delivering a 30-50% improvement in
lumen maintenance over these conventional systems. By maintaining higher
light levels across the entire published life of the lamp, the system delivers
significant value to the end user in three key ways:

• 30-50% IMPROVED LUMEN MAINTENANCE LEADS UP
TO 50% LESS LAMP REPLACEMENT COSTS
• 56% MORE LUMENS ENABLES THE USE OF
UP TO 36% FEWER FIXTURES

Lumen Maintenance Comparison
100%

86%

86%
% INITIAL LUMENS

The key to understanding the true value of this innovation is something
called "lumen maintenance," or the lamp/ballast system’s ability to minimize
light output depreciation over the life of the lamp. Conventional HID systems –
magnetic ballasts driving probe start metal halide lamps – typically experience a
50-60% fall-off in light output over the published life of the lamp. This fall-off can
lead to excessive maintenance costs due to the need for frequent re-lamping,
and inefficient energy usage throughout the life of the system.

ELECTRONIC E-REG®
IMPROVED LUMEN MAINTENANCE = LESS LAMP MAINTENANCE
Most lighting systems are designed on the basis of mean or“average” light
output of the lamp. For metal halide (MH) lamps, this mean light output, as
measured in lumens, defined at 40% of the lamp’s rated life. Since most
medium wattage MH lamps are rated at 20,000 hours of lamp life, mean
lumens are advertised at 8,000 hours of lamp life.
As lumens fall off after the 8,000 hr. design point, the lighting level for many
applications may become unacceptable, resulting in the need for re-lamping
significantly prior to reaching the 20,000 hr. rated life of the lamp.
Because of Electronic E-Reg®’s relatively flat lumen depreciation characteristic, (i.e., better lumen maintenance), early re-lamping is unnecessary, resulting
in a more cost-effective lighting system. In the example below, consider
identical installations with 400 fixtures: one with magnetic ballasts where
lamps are replaced at 12,000 hours, and a second where lamp life is
extended to 18,000 hours.

Conventional Magnetic Pulse Start
®

In this example, Electronic E-Reg
would save on average $10 per fixture,
per year, just in reduced maintenance
costs! The assumption was made that
an equal number of fixtures were used.
Next, consider the total consequences
of producing more light, longer, with
fewer fixtures… and discover its true
advantage.

A 400W Electronic E-Reg® system produces up to 56% more mean lumens
over conventional probe start systems using the same wattage lamps. Taking
advantage of this performance benefit, the overall fixture count can be

reduced by up to 36% without sacrificing light levels. Plus, fewer fixtures
also have a dramatic impact on both energy and maintenance costs, leading
to significantly lower overall operating costs.

CONTROLLABILITY
Electronic E-Reg® is dimmable – down to 50% of
nominal lamp power, with no noticeable loss in color
characteristics. With 0-10V dimming, and compatible
with a host of products from most control manufacturers,
Electronic E-Reg® brings new flexibility and energysaving strategies, such as daylight harvesting and
occupancy sensing, to applications in the industrial,
educational, government, hospitality, commercial and
retail sectors.

DIMMING FEATURE
With 0-10V interface, the Electronic E-Reg® electronic ballasts offer the capability to dim the lamp by
lowering the wattage lamp, reducing energy consumption of the light fixture by up to 50%.This interface
can be used with either a commercially available 0-10V dimming control, a 0-10V DC power supply,
or with a switch. An open switch provides full lamp power and a closed switch, short-circuiting the 0-10V
wires, yields 50% lamp power. Control devices such as relays and occupancy sensors may also be
used.
A potentiometer may also be used. However, the value of the potentiometer is dependent on the number
of ballasts connected. Consult Hubbell Industrial for guidance. In accordance with the requirements
of the HID lamp manufacturers and NEMA, the dimming feature includes a time delay to allow the HID
lamp to warm up for 15 minutes at full power before the lamps will be allowed to dim, regardless of
the level of the 0-10V signal.

Combining decades of Hubbell Industrial optic design expertise, delivering more light to work areas with

charges. This over-driving and under-driving of the lamp is one of the
biggest causes of loss of light as the lamp ages.

The second benefit comes from our patented ignitor. Igniting a lamp using
high voltage is just a more effective way to operate and results in smoother
starting and warm-up. This means less electrode damage per start, the
same electrode damage that darkens the arc tube walls and limits light
output. To quantify this unique system benefit, Hubbell has developed an

BALLAST SYSTEM ADVANTAGE
WHY ELECTRO-REG® IS MORE EFFICIENT.

Lamp Wattage Regulation

A standard lamp operated on the Electro-Reg® ballast system will produce
more light for more hours on the job than any other system available. To
translate this into energy savings, apply the EOF-er factor when doing lighting
calculations. You will find that it takes fewer fixtures to achieve the target
lighting level with the Electro-Reg® system than with competing alternatives.
Since the ballast uses about the same total wattage as the comparable CWA
or Pulse Start CWA, fewer fixtures result in less energy used for the job. The
fixture comparison charts on the following page illustrate the effect this
reduction in fixtures can have. At today’s energy prices the result is significant.
Who knows what energy prices will be tomorrow?

dropout to begin with? A sudden dip in line voltage may extinguish the lamp
arc, requiring most HID fixtures to cool down (from 2 to 15 minutes), re-strike
and then warm up. The Electro-Reg® ballast tolerates up to a 59% drop in line
voltage without losing the arc. CWA and CWA Pulse Start both are about 38%
of line voltage. This means that the chance of having HID lamp dropout is
much less with an Electro-Reg® ballast system.
Any facility with unstable power or large electric motors has the potential to
experience lamp dropout. Help prevent this potentially dangerous situation,

for the retail environment.

The comparisons to the left show the
Hubbell V-Spec when compared to the
popular linear fluorescent highbay fixtures.

Advantages to an HID system
include:
• EASE OF MAINTENANCE
Typical fluorescent systems will have
twice the number of fixtures and 10 to
15 times more lamps, resulting in much
higher on-going maintenance costs.
Contrast a typical warehouse with 250
HID fixtures or 440 fluorescent highbays.
Each fluorescent has six lamps while the
HID only have one. That means 250 HID
lamps to maintain vs. 2640!
• WIDE TEMPERATURE RANGE
Metal halide lamps operate reliably
in unconditioned spaces where
temperatures can exceed 149°F or
fall below -40°F. Light output from
fluorescent lamps will drop off in
extreme temperatures.
• FREEZER APPLICATIONS
Metal halide lamp/ballast can be reliable
used down to –40°C for Electro-Reg®
and HPS and down to –20°C for standard
metal halide.
• AMBIENT TEMPERATURE SUITABILITY
HID fixtures are UL tested for ambient
temperature ranges of as high as 65°C,
while fluorescent highbay fixtures are
normally tested for only 25°C ambient
temperature.
• LOWER INSTALLED COST
Metal halide highbay systems are almost
always less expensive to install. A typical
HID system will have half the number of
fixtures as a equivalent fluorescent
systems.
• LARGER LUMEN PACKAGES Mounting
heights of more than 20 to 25 feet may
lend themselves better to metal halide.
• SEVERE ENVIRONMENTS

expressly for applications that are
corrosive, dirty, are wet locations, are
subject to vibration or violent impact,
or required hazardous location ratings.
Fluorescent highbay fixtures are
normally rated for damp locations only.

JUST WHAT IS THE DIFFERENCE BETWEEN
HID vs. FLUORESCENT LIGHTING?
There are certain advantages and disadvantages when you need to decide between HID or
fluorescent lighting. The right choice has a lot to do with height from the work surface, desired
light distribution, type of light, maintenance cost expectations, dirty/dusty ambient environments,
and hot or cold ambient environments.

If your application is one that meets one or more of these performance criteria, then HID is the
first option to explore.

HID LIGHTING ADVANTAGES
• WIDER TEMPERATURE OPERATING RANGES Metal halide lamps operate
reliably in unconditioned spaces where temperatures can exceed 149°F or fall
below -40°F. Light output from fluorescent lamps will drop off in extreme
temperatures.
• FREEZER APPLICATIONS Metal halide lamp/ballast can be reliably used
down to -40°C for Electro-Reg™ and HPS and down to -20°C for standard
metal halide.

FLUORESCENT LIGHTING WORKS WITHIN

• CONTROL FRIENDLY The instant-on
capability of fluorescent lamps makes them good
for use with occupancy sensors and

• BROAD AMBIENT TEMPERATURE SUITABILITY HID fixtures are UL tested
for ambient temperatures as high as 65°C, while fluorescent highbay fixtures
are normally tested for only 25°C ambient temperature.

• LUMEN MAINTENANCE T5 and T8
fluorescent lamps lose 5-6% of their lumen
output between their rated initial and maintained
lumens (maintained lumens are calculated at

• LOWER INSTALLED COST Metal halide highbay systems are typically less

highbay and lowbay locations. These components can easily
be installed or relocated by simply unplugging and reinstalling
connections.
™

Hubbell provides its fixtures hardwired with the ACS
Flex3+™ Fixture Cord Drop, ready to plug into the Flex3+™
Distribution Cables and Extender Cables (order directly
from ACS).
Common Flex3+™ applications include highbay and lowbay
lighting fixtures in industrial locations such as factories
or warehouses and retail locations such as supermarkets
and big box stores. All components in the Flex3+™ system
are rated for use on 20 ampere branch circuits and are UL
listed and labeled.

Hubbell’s Extreme Lighting provides lighting solutions for demanding conditions. Markets falling in this category are
Harsh, Hazardous, Marine, Cleanroom, and Specialty (e.g., warning or obstruction). There is overlap potential with all of
these markets. For example, a Harsh Environment such as a sewage treatment plant may also be a Hazardous location.
Cleanrooms can be Hazardous, and Marine are also Harsh.
Typical installations served by Extreme lighting are power plants, waste water, and sewage treatment plants, food
processing, petrochemical and chemical plants, shipboard, grain processing, pharmaceuticals, semi-conductor facilities,
offshore platforms, FPSOs, pulp & paper plants, and coastal areas, just to name a few.

There are many claims in the lighting industry that luminaires can withstand 400, 600, or 1000 PSI. It is important to
know parameters to which these tests were conducted, because nozzle size, flow rate/pressure, distance and time play a
key part in results. For example, a 1/2” nozzle of 1,000 PSI at 6 inches could cut a solid brick, but the same pressure hose
from a mist nozzle may not penetrate a sheet of paper from 6 feet.
Hubbell Lighting makes every effort to credibly test our luminaires by being listed with certified testing authorities such
as CSA and UL. Typical washdown listings include UL 1598A Marine Outdoor, NEMA 4, Ingress Protection IPx6 and IPx5.
Test

These tests are designed to be performed on an empty enclosure. Hose test is performed on a static enclosure without any pressure changes in the housing.
IP Tests are dynamic, and pressure changes take place during the test. When power is terminated, the luminaire housing creates a negative pressure (vacuum) which
attempts to pull in any external water or dust surrounding the luminaire.

Temperature Codes (T-Codes)

The ignition temperature or auto-ignition temperature (AIT) is the minimum temperature required to initiate or cause
self-sustained combustion in a substance without any apparent source of ignition. The lowest published ignition
temperature should be the one used to determine the acceptability of equipment. This is of particular concern when
selecting heat producing equipment such as lighting fixtures or motors which may generate sufficient heat to ignite the
surrounding atmosphere.
Class I and Class II, areas use T-Codes or are subject to maximum temperature limitations as shown in the following
chart. North America and the IEC are consistent in their temperature or T-Codes. However unlike the IEC, North America
includes incremental values as shown below.

The IEC uses the term “IP” to identify the environmental protection of an enclosure. This is defined in IEC Standard
529 and is referenced by the CEC®. NEMA Enclosure Types may be converted to IP code designations.
The IP classification system designates, by means of a number, the degree of protection provided by an enclosure and
the electrical equipment against physical contact, foreign bodies and water ingress.
The protection classes for electrical equipment in respect of:
1. Protection of persons against contact with live or moving parts. (Physical contact protection)
2. Protection against ingress of solid foreign bodies. (Foreign body protection)
3. Protection against ingress of water. (Water protection)
IF a code digit does not have to be given it should be replaced with the letter “X”.

Environmental Lighting

The key point to note with IP classification is that the tests are dynamic. Prior to testing, the luminiares are operated
with the highest rated lamp combination for one hour. The luminaires are powered down just prior to testing and this
creates a vacuum in the luminaire, or causes it to contract. Therefore, the luminaire is making every attempt to pull in
whatever dust or water it is being subjected to during the test. These are very viable and realistic tests.
The IP code indicates the degree of protection provided by enclosures for electrical equipment.
The first numeral indicates protection of persons against access to dangerous parts and protection of internal
equipment against the ingress of solid foreign objects.

HAZARDOUS NEC
Hazardous (Classified) Locations

CLASS I LOCATIONS

Class I locations are those in which flammable gases or
vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. The
term “gases or vapors” is used because of common usage
in the English language. The term “gases” is commonly
used to refer to materials that are in a gaseous state under
normal atmospheric conditions, such as hydrogen and methane. The term “vapors” refers to the gases over a material
that is a liquid under normal atmospheric conditions (such as
gasoline) but which emits gases within the flammable range
under these same atmospheric conditions.

CLASS I, DIVISIONS 1 AND 2
GROUPS A, B, C, AND D LOCATIONS

General
The subdivision of Class I into two divisions identifies the
likelihood or risk that an ignitable concentration of gases or
vapors will be in the location. Division 1 identifies locations
where the risk is high or medium. Division 2 identifies
locations where there is a small but still finite risk. If the
risk is extremely low, the location is not considered a
hazardous location. A single family home typifies such a
location with natural gas or propane as the energy source
for heating. The gas could, and on extremely rare occasions does leak into the home, and an explosion could occur.
However the risk is so low (because of the safety
systems built into the gas supply and heating equipment)
that such locations are not classified as hazardous.
Division 1
Class I, Division 1 locations are those where the explosion
hazard exists under normal operating conditions. The
area may be hazardous all or most of the time, or it may
only be hazardous some of the time. Division 1 also includes locations where breakdown or faulty operation

of electrical equipment or processes might release ignitable
concentrations of flammable gases or vapors, and might
also cause simultaneous failure of electrical equipment
in such a way as to directly cause the electrical equipment
to become a source of ignition. An example of such a location
might be an area where a flammable liquid is stored under cryogenic conditions, and a leak of the extremely low
temperature liquid directly onto electrical equipment could
cause failure of the electrical equipment at the same
time the vapors of the evaporating liquid are within the
flammable range.
Division 2
Class I, Division 2 locations are those where ignitable
concentrations of flammable gases or vapors are not
normally present, but could be present in the event of a
fault, such as a leak at a valve in a pipeline carrying flammable liquids. Division 2 locations also often exist around
Division 1 locations where there is no barrier or partition
to separate the Division 1 space from a non-hazardous
location, or where ventilation failure (an abnormal
condition) might extend the area where flammables exist
under normal conditions.
Electrical equipment approved for Class I, Division 1 locations
is also suitable for use in Division 2 locations.

CLASS II LOCATIONS

Class II locations are those that are hazardous because of
the presence of combustible dust. Note that the dust must
be present in sufficient quantities for a fire or explosion
hazard to exist. The fact that there is some combustible
dust present does not mean a Class II hazardous location
exists. To be considered a “dust” the combustible material
must exist as a finely divided solid of 420 microns (0.420
mm) or less. Such a dust will pass through a No. 40 U.S.
sieve.

CLASS II, DIVISIONS 1 AND 2
GROUPS E, F, AND G LOCATIONS

General
Just as in Class I, Divisions 1 and 2, the subdivision of Class
II into Divisions 1 and 2 identifies the likelihood that
there will be an explosion hazard.

Environmental Lighting

Hazardous locations are those locations where fire or
explosion hazards may exist due to flammable gases or
vapors, flammable liquids, combustible dust, or ignitable
fibers or flyings. Although flammable gases and vapors,
and combustible dusts exist almost everywhere, they are
usually present only in minute quantities, much less than
necessary for a fire or explosion hazard to exist. Thus,
the presence of a flammable gas or vapor, or combustible dust, does not in itself define a hazardous location.
These materials must be present in sufficient quantities
(concentrations) to present a potential explosion hazard.
Locations where there is an explosion hazard because of
the presence of high explosives, such as blasting agents
and munitions, are not classified as hazardous locations.
There are standards covering the handling and use of such
materials, and some of these require electrical equipment
suitable for use in hazardous locations. This is because such
equipment provides a greater degree of safety than ordinary
location or general-purpose equipment, not because such
equipment has been tested for use in the presence of high
explosives. In a like manner, locations made hazardous
because of the presence of pyrophoric materials, such as
some phosphorous compounds and finely divided metal
powders are not classified as hazardous locations. Pyrophoric
is defined in the dictionary as “igniting spontaneously” or
“emitting sparks when scratched or struck, especially with
steel”. Where pyrophoric material or high explosives are
present, precautions beyond those in the electrical codes
are necessary.

Division 1
A Class II, Division 1 location is one where combustible
dust is normally in suspension in the air in sufficient
quantities to produce ignitable mixtures, or where
mechanical failure or abnormal operation of equipment
or machinery might cause an explosive or ignitable dustair mixture to be produced, and might also provide a
source of ignition through simultaneous failure of electrical equipment. A Class II, Division 1 location also exists
where combustible dusts of an electrically conductive
nature may be present in hazardous quantities (Group
E locations). The term “hazardous quantity” is intended
to mean those locations where the dust may not be in
suspension in the air in sufficient quantity to cause an
explosion, but might have settled on electrical equipment
so that the electrically conductive particles can penetrate
the openings in the electrical equipment enclosure and
cause an electrical failure, or where the dust can get
into motor bearings and cause excessive temperatures
because of bearing failure.

101

HAZARDOUS NEC
Hazardous (Classified) Locations

SEVERE

Division 2
A Class ll, Division 2 location is one where combustible
dust is not normally in the air in quantities sufficient to
produce explosive or ignitable mixtures, and dust accumulations are not normally sufficient to interfere with
the normal operation of electrical equipment, such as
clogging ventilating openings or causing bearing failure.
It includes locations where combustible dust may be in
suspension in the air only as a result of infrequent malfunctioning of handling or processing equipment, and
those locations where dust accumulation may be on or in
the vicinity of the electrical equipment and may be sufficient to interfere with the safe dissipation of heat from
the equipment, or may be ignitable by abnormal operation
or failure of the electrical equipment.
Class II, Groups E, F, and G
The division into three groups in Class II locations is for
the same reasons Class I locations are divided into Groups
A, B, C, and D: equipment design and area classification.
However, the three Class II groups are based on different
characteristics than the four Class I groups because the
design of dust-ignition proof equipment for Class II
locations is based on different principles than the design
of explosion proof equipment for Class I locations. In
Class II locations the ignition temperature of the dust,
the electrical conductivity of the dust, and the thermal
blanketing effect the dust can have on heat-producing
equipment, such as lighting fixtures and motors are the
deciding factors in determining the Class II group.
Group E
Group E dusts include the metal dusts, such as aluminum
and magnesium. In addition to being highly abrasive, and
thus likely to cause overheating of motor bearings if the
dust gets into the bearing, Group E dusts are electrically
conductive. If they are allowed to enter an enclosure,
they can cause electrical failure of the equipment.
Group F
The Group F dusts are carbonaceous, the primary dust in
this group being coal dust. These dusts have somewhat
lower ignition temperatures than the Group E dusts and
a layer of a Group F dust has a higher thermal insulating
value than a layer of a Group E dust, thus requiring more
careful control of the temperature on the surface of the
equipment. Such dusts are semi-conductive but this is not
usually a factor for equipment rated 600 volts and less.

102

Group G
The Group G dusts include plastic dusts, most chemical
dusts, and food and grain dusts. They are not electrically
conductive. These dusts, in general, have the highest
thermal insulating characteristics and the lowest ignition
temperatures. Thus, dust ignition proof equipment
for use in Group G atmospheres must have the lowest
surface temperatures to prevent ignition of a dust layer
by the heat generated within the equipment. Because of
the different design characteristics, equipment suitable
for Class I locations is not necessarily suitable for Class II
locations, and equipment suitable for Class II locations is
not necessarily suitable for Class I locations. The equipment
must be approved for each class and group of location
involved. Much equipment suitable for Class I locations
is also suitable for Class II locations, and is so marked,
although when used in Class II locations there may be
restrictions, such as lower maximum lamp wattage to
maintain the lower surface temperature needed for
equipment in dust atmospheres.
In Class II areas all products must operate at temperatures
based on whether they are heat producing or subject to
overloading or not, and based on the Group which they
fall under. Class III products in all cases must operate
below 165째 C.

CLASS III LOCATIONS

Class III locations are those that are hazardous because
of the presence of easily ignitable fibers or flyings, but in
which the fibers or flyings are not likely to be in suspension in
the air in quantities sufficient to produce ignitable mixtures.
Easily ignitable fibers and flyings present a fire but not
an explosion hazard. A typical example of this type of
material is the cotton lint that accumulates in the lint
trap of clothes dryers. Listed clothes dryers are designed
so that even if the lint ignites, the fire will be contained
within the dryer enclosure.

CLASS III, DIVISIONS 1 AND 2

Division 1
This is a location where the equipment producing the
ignitable fibers or flyings is located (near textile mill
machinery, for example) or where the material is handled
(for example, where the material is stuffed into bags).
Division 2
This is a location where the easily ignitable fibers are
stored or handled, except in manufacturing processes
(which is Division 1).
Class III Groups
There are no groups in Class III locations.

MEASURING OPEN CIRCUIT VOLTAGE

To determine if the ballast is supplying proper

starting voltage to the lamp, an open circuit voltage test is required. The proper
test procedure is:

mercury ballasts

If the proper input voltage is measured, most HID fixture problems can be

1 Measure input voltage (V1) to verify rated input voltage is being applied
to the ballast.
2 If the ballast has an ignitor (HPS, low wattage MH - 35W to 150W - or

capacitor (1000 pF or larger) across the voltmeter input to protect the
meter from the hight voltage ignitor pulse. Some ballasts have an integral
or built-in ignitor. If you are not sure if an ignitor is used, put a capacitor across the meter for all open circuit voltage measurements.
3 With the lamp out of the socket and the voltage applied to the ballast or
the proper tap of the ballast with multiple voltage inputs, read the voltage (V2) between the lamp socket center pin and shell. Some lamp
socket shells are split. Make sure connection is being made to the active
part. The reading must be within test limits shown in the table below.
Open circuit voltage must be measured with a TRUE RMS voltmeter to
provide an accurate reading.
4 Constant wattage (CWA, CWI) ballasts have a capacitor in series with the
lamp. If the capacitor is open there will be no open circuit voltage.

An HID ballast is designed to limit current at the specified value range.

To assure that the ballast is delivering the proper current under lamp starting conditions, a measurement may be taken by connecting an ammeter
between the lamp socket center pin and the socket shell with rated voltage
applied to the ballast. If available, a lamp socket adapter may be used as
described in the open circuit voltage test.

1 Energize ballast with proper rated input voltage.
2 Measure current with ammeter at A1 and A2 as shown in the diagram right.
3 Readings must be withing test limits shown right.

A clamp-on TRUE RMS ammeter may also be used to perform this test by placing an 18 gauge wire between the lamp and common leads of the ballast. When
using a clamp-on ammeter for this measurement, be certain the meter is not
near the ballast magnetic field or any steel object that may affect the reading.

The short circuit current test will also determine a defective capacitor in
constant wattage circuits. A shorted capacitor will result in high short circuit current, while an open capacitor or low value capacitor will result in no
or low short circuit current.
